ROTARY GHURN,

To all whom it may concern Be it known that I,,OLIVER'- E. HARR1s,"a citizen of the United States, residing at Abingdon, in the county of Knox and State of Illinois, have invented certa'in new and useful Improvements in Rotary Churns, of which the following is a specification.

This invention relates to improvements in devices for mixing and disintegrating substances or compounds, such as ehurn 'mix ing machines or devices of various kinds and sizes, and has as one ofit's objects to improve the construction and increase the ef-' ficiency and utility of devices of thischar- 'acter.

Another object of the invention is to pro vide a simply constructed device,'whereby the compound or material. may be mixed or the particles disintegrated according'to' the nature of the material oncompound', and wherein the parts are readily separable. for cleansingor repairs. 1

With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shownand described and then specifically pointed out in the claim.

The improved device may be applied Without material structural change to churns and similar machines and tomixing or disintegrating devices of various forms, such as concrete mixers, cement mixers or tlie like, and it is not desired therefore to limit the invention in. any manner in this respect. The device is particularly applicable for use as a churn and for the purpose of illustration is shown thus. applied, and in. the drawings illustrative ofthe preferred em bodiment of the invention, Figure 1 is a sectional elevation. Fig. 2 is a. transverse section on'the line 2'2 of Fig. 1-.- F i'g 3* is a section on' the line 33 of'Fig. 1 ofone of the supporting members and the blades of the outer mixer or disintegrating portion of the device. 7

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters. The improved device will be erected in a suitable receptacle for the material Ito be mixed or disintegrated, such as a tub'lO, when the device is applied to a churn. Thebottom 11 of the tub 10 is provided with a step 12 to receive the lower end'13 of a vertical shaft 14. The shaft 14 extends for a Specification of Letters Patent;

considerable distance above the top of the tub andis' provided at its upper end with a relatively small beveled pinion 15, the shaft 14 having a square upper terminal 16 to detachab'ly support" the pinion, the object to be hereafter explained. Ihe portion of the shaft within the tub 10 is likewise formed square, as shown at 17, and with a reduced lower portion or journal 18" between the square portion 17 and the" step engaging portion 13. Surrounding'the shaft 14 is a sleeve 19, the latter beingfso located that it projects for" a distance above the upper line of the tub and is formed witha square bearing 20 to cletacha'bly receive a gear pinion 22. The tub 10 is provided with a top formed in two sections 23''24, the 'section 23 havinga half beanset collar 25 to engage partially around the sleeve 19 while the cover 241's provided with asimilar half collar or hearing 26 to engage partially around the sleeve 19. The two members 2'5'2'6 e ntii'eliy encompass the sleeve 19. At its lower end the sleeve 19 is formed with a plurality ofradi-a l arms 27 which extend toward the walls of the title. A collar 28 is mounted for rotation upon the bearing portion 18 of" the shaft and is formedwith a plurality of radial arms 29 corresponding to the arms 27 Dasha blades 30" are connectedtothe terminals of the arnis 27 -29 and operate in close proximity to the inner face of the tub. Mounted upon" the square portion 17 of the shaftnear its upper end vided with a plurality of-"radial arms 34;,

similar to the arms 32; A- plurality ofslats or d'asher members 35ar'econnected to the arms 32'34, as shown. The arms 32-34: are s'hor ter'thanthe arms 27 29 sothat the outermost" slats" 35 operate-within the space bet-ween the dasher blades 30,- as shown.

The blades '30 are relatively "thin and flatand the outer portion of the arms 21-28; are heat slightly so that the blades 30 operate tangentially of the shaft 14 and of the tub 10, illustrated in Figs? 2 and 3; By

thus arranging the blades 30 to operate tangentially of the tub 10, the material which comes in contact with the blades is moved outwardly toward the inner walls of the tub when the blades are moved in one direction,

be readily removed and applied to the tub without interfering with the bracket members. The members 36 are connected by a transverse member 37 with bearings 3839 above the portion 37 the bearings adapted to receive an operating shaft 40 havingan operating crank 41. At its inner end the shaft 40 is formed with a square bearing 42 to receive a beveled gear 43 which engages with the pinions 15-22, as shown. Extending above the bearing 39 is a standard 44 having a flat upper bearing face 45 from which a pin 46 extends. Bearing upon the portion 45 of the standard is an arm 47 having an aperture to receive the pin 46 and with a bearing 48 to receive an upwardly directed journal on the upper end of the shaft 14. A clamp screw 49 operates through the member 47 and into a threaded aperture in the bearing 45 to enable the member 47 to be clamped in position upon the standard 44. By this means the upper end of the shaft 14 is firmly supported in position and may be rotated in either direction. By this arrangement, it will be obvious that when motion is imparted to the shaft 40 by the crank 41, the gear 43 will be actuated and transmit motion in opposite directions to the pinions 15-22. The pinion 15 being attached to the shaft 14 will rotate the latter in the samedirection, while the pinion 22 being attached to the sleeve 19 will actuate the latter in the opposite direction. Thus the blades 30 will rotate in one direction while the slats 35 will be actuated in the opposite direction and thus produce a rapid and thorough agitation of any material which may be deposited in the tub and thoroughly mixing and inter- 4 mingling the same and, when employed as a churn, thoroughly and positively separating the butter particles from the cream. The slats 35 being arranged radially of the shaft 14 mix the material which comesin contact therewith without appreciably moving it to ward the outer walls of the receptacle or to ward the shaft no matter in which direction the shaft and the slats may be rotated, while theblades 30, being arranged tangentially of the tub and of the shaft, move the portion of copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,'

the material with which they come in contact outwardly or toward the walls of the receptacle when rotated in one direction and move the portion of the material with which they come in contact inwardly toward the shaft when the motion is reversed. By this means, the mixing is greatly accelerated by simply reversing the motion of the mechanism at intervals, as will be obvious.

When the device is to be dismembered or the parts separated, the cover members 2324 are removed and the bolt 49 detached and the member 47 elevated uponits pin 46 to release the shaft 14. The pinion 15 and the shaft 14 may then be removed endwise leaving the pinion 22, wheel 43 and the sleeve 19, together with its attachments, and the sleeves 33 and their attachments, readily removable, as will be obvious. By this means the parts may. be readily cleansed or repaired, or broken parts renewed without discarding the remainder of the device.

The sleeve 19, together with its arms 27, forms a spider-like device while the collar 28 and its arm 29 form another spider-like device. The collar 31 with its arms 32 like wise forms a separate spider-like device while the collar 33'with its arms 34 forms another spider-like device, as illustrated more clearly inFigs. 2 and 3/ The improved device is simple in construction, can be inexpensively manufactured and applied for any purpose requiring the mixing or disintegrating of particles.

Having thus described the invention, what is claimed as new is: s

In a churn, an inner dasher comprising a plurality of radial arms each carrying vertically spaced heaters, and an outer dasher comprising a plurality of radial arms directed obliquely to the longitudinal planes of the arms where they project beyond the arms of the inner dasher, and vertical blades secured to said obliquely directed portions, the sides of said blades extending in parallel relation, and means for reversibly rotating said dashers in opposite directions, whereby material is moved toward the center of the .dasher when the same are rotated in one di- OLIVER E.
